Re: [Discuss-gnuradio] question about the synchronization symbol used in ofdm example

Hello Aditya: I think it should be shifted.In the transmitter of the OFDM,the ifft operation is adopted. Another phenomenon I have found that the result of the input data go through the FFT block (gnuradio)isn't same to the result in matlab(just ifft(data))
